Anybody feel the same

I am waiting on my doctor to call me back, but yesterday I went to the grocery store and my blood pressure was "at risk" according to the machine it was 136/89 I believe.. and my heart rate was 107bpm. Anyways it made me paranoid and I downloaded some app a coworker told me about and it said the same thing and then this morning I checked and it said 150/97 so I have no clue of the app is accurate or not..I had other co workers try it and theirs is normal. But if mine is really high I don't have a head ache or anything just really tired and my feet and hands hurt pretty bad..I just wanted some input from you lady's thank you in advance...
